Anatomy Physiology

  • Bird in flight.  Flight is a mode of locomotion that has co-evolved in several lineages in the animal kingdom.  Here, we see a roseate spoonbill (Platalea ajaja) in flight over Everglades National Park in Florida.  Photo credit: Brian K. Mealey.

    It's a bird! It's a plane! It's biomechanics!

    Learning Objectives
    Students will be able to:
    • identify and define forces that act on an object in flight.
    • understand the definition of Newton’s third law of motion, which states that with every action there is an equal and opposite reaction, and apply this principle to explain pressure differences and lift generation.
    • generate hypotheses about animal flight efficiency based on examining morphology (anatomy).
    • generate hypotheses correlating wing size and performance during flight.
    • apply their understanding of wing designs and wing relationships to total mass.
    • compare flight principles among animals to understand the co-evolution in several animal groups.

    The Science Behind the ACTN3 Polymorphism

    Learning Objectives
    This article accompanies the lesson "The ACTN3 Polymorphism: Applications in Genetics and Physiology Teaching Laboratories." Learning objectives for the lesson include:
    1. Test hypotheses related to the role of ACTN3 in skeletal muscle function.
    2. Explain how polymorphic variants of the ACTN3 gene affect protein structure and function.
    3. List and explain the differences between fast twitch and slow twitch muscle fibers.
    4. List and explain possible roles of the ACTN3 protein in skeletal muscle function.
    5. Find and analyze relevant scientific publications about the relationship between ACTN3 genotype and muscle function.
    6. Formulate hypotheses related to the relationship between ACTN3 genotype and skeletal muscle function.
    7. Design experiments to test hypotheses about the role of ACTN3 in skeletal muscle function.
    8. Statistically analyze experimental results using relevant software.
    9. Present experimental results in writing.

  • In small groups students brainstorm a list of responses to the prompt and then exchange their lists with another group to circle sex characteristics and star gender characteristics.  The image has whiteboards completed by students.

    Sex and gender: What does it mean to be female or male?

    Learning Objectives
    • Students will be able to distinguish between sex and gender, and apply each term appropriately.
    • Students will be able to compare and contrast levels of sexual determination.
    • Students will be able to critique societal misrepresentations surrounding sex, gender, and gender identity.
